Replacement pH Probe

The PS183-20B is a replacement pH Probe designed to work with our PS90S Dip pH Electrode system.

The probe has a 3/4" BSP mounting thread and is designed with an electrode guard to prevent the glass bulb being compromised from mechanical damage. It has a double junction to resist electrode poisoning and a very fast response time using a free flowing annular ceramic junction.

With the 3/4" BSP thread, it can easily be removed from the dip pH electrode system for calibration or service.

Please note, the PS183-20B was formerly called model number PS183-750-20B; but is now referred to the more straight forward PS183-20B.

The PS183-20B replacement pH probe is a double junction, combination pH probe in rugged industrial housing, manufactured in PVC.

The probe has the 3/4" BSP thread at the base so it can easily be screwed into one of our dip assemblies; most commonly the PS90S Submersible pH electrode system.

The PS183-20B construction includes an electrode guard to prevent mechanical damage to the glass bulb, while still allowing excellent contact with the solution to be measured. With a non-fouling annular ceramic junction the response time of the pH probe is excellent and with the non fouling junction it means that this pH sensor has no problems with continual pH measurement.

The PS183-20B is designed as a replacement pH Probe insert for use with the PS90S dip pH electrode assembly. It is designed for mounting in open tanks, pits, sumps or any other non-pressurised vessel. These are commonly mounted within tanks that have dosing pumps, industrial mixers or agitators mounted into them. We would recommend that where an industrial mixer or agitator is present, the liquid to be monitored is reasonably clear of solids or particulates that may damage the glass. In instances where particulate matter is present, we would suggest using our replacement tuff tip pH probe model PTT183-20B.

The PS183-20B is also designed to be resistant to electrode poisoning from solutions which would otherwise react with a silver, silver chloride electrode reference.

Replacement pH Probe Model PS183-20B Features & Benefits

The PS183-20B replacement pH probe with non-fouling annular reference and double junction. This sealed pH probe is designed as a replacement pH probe insert for use with a PS90S dip pH electrode system for submersion in industrial applications that use non-pressurised vessels.

The pH probe has a built in electrode guard to resist against mechanical damage. These probes are frequently mounted in tanks where agitators or industrial mixers are present. This pH electrode is designed for rugged applications and gives precision measurements across the 0-13pH range and is suitable for a temperature range of 0-50°C.

The PS183-20B is supplied with 20 feet of connecting cable as standard and a BNC plug for easy connection to our pH instrument range.
